How Network Load Balancing Works

When you configure the application Use NLB, client applications with the address NLB cluster address rather than the address Participation NLB cluster nodes. That NLB cluster address is a virtual address NLB cluster shared between hosts.

NLB following guide traffic Info: All the NLB cluster hosts receive Incoming traffic, but only one node

Cluster, which is determined by the NLB Process, will accept the traffic. All other nodes NLB cluster will drop traffic.

NLB cluster nodes that relies on the communication and configuration port policy Related settings. With these settings, you can decide whether to use a specific port traffic, Are any specific node agreement accepted or acceptable in the cluster and response.

NLB also send traffic to use the node based on the current node. New traffic is directed to the node we use the least. For example, if you have a four-node cluster where three nodes are From 10 clients in response to a request, a node in response to a request from five clients, the node With fewer customers will get more incoming traffic, until evenly balanced usage across Node.
